avcodec/dca_core: Don't use too big max_depth in get_vlc2()
Most of the VLCs used here have a max_depth of two;
some have a max_depth of one. Therefore one can just use two
and avoid the runtime check for whether one should
perform another round of LUT lookup in case the first read
did not read a complete codeword.
